Q
In two sentences or less describe HCI.
A
- HCI is the study of interactions between a human and a computer.
- It is comprised of areas such as User Interface design, Psychology and Robotics to name a few.
2
Q
- Why is HCI important?
A
- It enables the development of usable technology for everyone.
3
Q
How is the Waterfall method modified to handle user interface development?
A
- It is modified by use of an iterative and flexible design process.
4
Q
Describe 3 variations of the Waterfall method for handling the evolutionary nature of user interface design.
A
- Modified Waterfall Method: User feedback is incorporated into each phase of the process.
- Agile Waterfall Method: Separates the development process into smaller, iterative cycles known as sprints, Each sprint focuses on delivering a functional and tested portion of the user interface design, which is then reviewed and refined in the subsequent sprints.
- Spiral Model: involves prototyping, testing, and gathering feedback before moving on to the next stage.
5
Q
What is user-interface design?
A
- The process of designing the visual and functional elements of digital interfaces
6
Q
What is meant by usability?
A
- refers to the extent to which a product or system can be used by its intended users to achieve specific goals with efficiency, effectiveness, and satisfaction.
7
Q
What is meant by the user-experience? Include examples.
A
- The overall experience that a user has when interacting with a product or service. A positive user experience can lead to increased user engagement, customer loyalty, and business success.
Some examples:
- Website design
- Mobile Apps
- Customer Service
8
Q
What are the 6 principles of usability?
A
- Learnability
- Efficiency
- Memorability
- Error prevention & Recovery
- User Satisfaction
- Accessibility
9
Q
What is a user-interface and what is its primary purpose?
A
- UI is the point of interaction between a user and a digital system or device.
- The primary purpose is to provide an intuitive and easy-to-use experience for the user.
10
Q
What is a prototype?
A
- An early or preliminary version of a product for the purpose of testing and evaluation.
11
Q
Describe the prototype loop.
A
- A process used in user interface design to refine and improve the design of a product or interface through rapid iteration and user feedback.
12
Q
- What is the purpose of each iteration of the prototype loop?
A
- Design: To create a prototype of the user interface.
- Test: Gather feedback from users and identify potential usability issues.
- Analyse: To Analyse the feedback and use this information to inform the next iteration design.
- Refine: To refine the prototype based on the feedback and data gathered during the test and analyse phrases.
13
Q
- Give three examples of different types of prototyping.
A
- Paper Prototyping:
- Digital Prototyping
- Physical Prototyping
14
Q
- What is low fidelity prototyping? Give 2 examples.
A
- The process of creating a basic, rough, and simple prototype of a product/system.
Two examples:
- Sketches & Wireframes
- Cardboard or Foam Models
15
Q
- What is high fidelity prototyping?
A
fidelity prototyping?
- Refers to the process of creating a detailed and fully functional prototype of a product or system.
16
Q
- Compare low fidelity to high fidelity.
A
- Fidelity: This is the main difference, which takes into consideration the level of detail & realism.
- Purpose: Low fidelity prototypes are often used in early design process to explore and test different ideas quickly and inexpensively.
- Cost : Low fidelity < High fidelity
- Realism
